Abstract: The effects of yray irradiation on the mechanical properties of HIPS/SBS blends have been investigated. The resuIts indicate that suitable irradiation resuIts in an increase of hardness and thermal deformation temperature of the blends with tensile strength and impact strength being remained ui1changed. When the dose of irradiation was too large the tensile strength and impact strength decreased markedly,the hardness and thermal deformation temperature increased too.

Key words: polystyrene, styrene-butadiene block copolymer, blend, γ-ray irradiation, mechan-ical property
